PUMIP.

Application filed August 18, 1931.

To all whom t may concern.'

Be it lrnown that l, ll/lnxnun P. Funnies, a citizen of the United States, and a resident of the city of New York, borough of Brochlyn, county of Kings, and State of New York, have invented a new and improved Pump, of which the following is a description.

My invention relates to a rotary pump and more particularly relates to a pump adapted for pumping viscous substances.

The general object of the invention is to provide a pump for the indicated purpose improved in various particulars whereby the flow of the viscous material will be cilitated and efficiency otherwise promoted.

The invention has also for an important object to provide a steam jacketed pump cylinder for the heating of the viscous ma terial and to utilize the steam as a motive fluid for turning the pump.

A. further object of the invention is to provide a pump in which the steam employed for heating and as a motive fluid is caused to mix with the pumped material and to have a siphoning action to assist the pump.

The nature of the invention and its distinctive features and advantages will more clearly appear as the description proceeds.

Reference is to be had to the accompany ing drawings forming a part of thisv specification, it being understood that the draw ings are merely illustrative of one example of the invention.

Figure 1 is a vertical section of a pump embodying my invention;

Figure 2 is a horizontal section on the line 2-2, Figure 1;

Figure 3 is a detail in vertical section on an enlarged scale as indicated by the line 3-3, Figure 1.

In carrying out my invention in accordance with the illustrated example, a cylinder body 1.() is provided, having an inner wall 11 spaced from the outer shell to provide a steam space 12 resulting' in a steam aclreted cylinder. The inner wall 11 is in practice preferably separate from the outer shell and has `an annular outwardly directed flange 13 at the bottom secured by bolts 14 which pass through the bottom of the shell 10 and through an annular peripheral flange 15 on grid or open-work guard 1G extending across the cylinder at the lower end. A steam pipe 17 leads from any suitable source Serial No. 493,370.

of supply (not shown) `into the steam space 12 il. 'vertical shaft 18 is provided centrally in the cylinder and carries blades 19 at the top and blades 20 at the lower end, the hubs of the blades being keyed on reduced threaded ent s of the shaft 18 and held by nuts 21. The shaft 18 turns in upper and lower bearings formed by the spiders 23 integral 'with the inner wall 11.

litigi/cl with the upper blades 19 is an annular .sl/ries of turbine blades 2li to which steam is* directed through oblique ports 25 leading from the steam space 12 through an annular flange 26 on the wall 11 at the top. '.lhe flange 2G is secured in the illustrated example by bolts 2l" and nuts 28, the bolts passing 'through a laterally directed annular flange 29 on the upper end of the outer shell 10 and through an annular lateru al flange 30 on a cylindrical extension 31 within which the upper blades 19 and turbine blades )Al revolve.` ".lhe extension 31 has connected to it in any suitable manner a pipe leading to any desired point of delivery for the pumped material. ln prac tice a drain coclr 33 may be provided on the outer shell 10 at the bottom to drain water of condensation from the steam space 12.

lllith the described construction steam from the pipe 17 will :lill the steam jacket and from the latter the steam will escape through the ports 25 and be directed against the blades 211 to turn the same and with them the blades 19, shaft 18, and blades 20. The blades 19 and 2O are at such an angle as to pump the viscous substance through the guard 16 to the extension 31 and pipe 32. The steam, it will be observed, thus functions to heat the pump cylinder and to drive the pump. rlhe steam is caused furthermore to mix with the pumped material in the extension 31 and pipe 32 to have'a sipl'ioning action to assist the pump.

ln use the pump is set bodily into a tank of the viscous material. to be pumped so that the heat may be utilized to the fullest extent not only in heating the material as it passes through the pump but also to heat the material in the tank.

l would state in conclusion that while the illustrated example constitutes a practical embodiment oil" my invention, l do not limit myself strictly to the exact details herein illustrated, since, manifestly, the same can be codsideribly 'varied without die time from the spirit of the invention as de ned in the appended claims. j

Having thus described my' invention, I claim;

1, A steam pump of the class described comprisin a jacketed pump cylinder bodily submergib e with its jacket in the material to pumped', .steamsupply meansufor the steam jacket of the cylinder, and drive means inv position :taba-submerged withy the submergenee of the cylinder and actuated by the ysteam Vescapingfrom the steam jacket.

v2;. -A pum of the class described including a cyliin' er, pumping means associated with.y the cylinder, a fluid-drivenmeans rigid with, the pumping means to actuate the same, steam-heating means associated with the cylinder, and means in advance of said fluid-driven meansto direct the steam from the1 heating means to said second-mentioned meansr after the steam leaves the heating means.

3. Ai pump of the class described including a lrigidi cylinder, a rotary pumping means Within the cylinder, a turbine rigid with saidpumping means beyond the cylinder, and means todirect a motive fluid to said turbine.

4. A pum of the class described including a oylin er, pumping means associated with the cylinder, means constituting an extension ofthe cylinder tol which the pumping means delivers, a turbine rigid with the pumping Ymeans vamd disposed Within the "second-mentioned means, and means to directa'motivelfluid against said turbine.

'5'. VA pump of the class-described including a steam-jacketed cylinder, rotary pumping means associated therewith, an extension on the cylinder to which the pump discharges, a turbine rigid with the pumping means and disposed Within said extension, and means to direct the steam from the steam jacket against said turbine.

6. A pump of the class described including a. cylinder having an outer shell and a separate inner wall spaced therefrom to forma steam jacket, said wall formed with annular flanges at the top and bottom, means securing the lower ange to the bottom of the; outer shell, an extension about said shell, means securing said extension to the shell and to the upper flange of the inner Wall, a rotary pump means associated with the cylinder, bearings rigid with said inner wall in which the pumping means turn, and aturbine rigid with the pumping means and disposed above the upper flange of the inner Wall, said flange having a port for the passage of steam from the steam jacket to the turbine, and means to supply steam to the steam jacket.

7. A pump of the classl described including an outer shell, an inner Wall spaced from the shell to provide a jacket and formed with an upper flange, bearings rigid with the inner Wall, rotary pumping means turning With said bearings, and a turbine rigid with the pumping means andf disposed on the said flange, said flange having a port to direct steam from the steam jacket to said turbine.
